tion or diaphragm, c, through which are drilled minute orifices, d, for passage of the gas.-

Above this diaphragm 4are the induction-holes e, which admit air to commingle' with the gas. n f denotes an inverted dome', the interior of which constitutes a chamber,'-g, for expansion ofthe coinmingled air and gas owing from the tube a, this chamber being covered by a flat roof or top plate, h. Immediatelybelow this. plate, or at the top of the chamber, is the series of eduction or jet-holes, i, at the lmouth or outer end of each of which the issuing jet of air and gas'is burned. j y

The tube a extends up through the chamber g, ter-l minating just below the plate h., as seen in the drawing, the gas issuing Be it known that I, WILLIAM JONES, of Chelsea, in of Suffolk, and State of Massachusetts, have invented an Improved Aero-Gas Burner; and I' do hereby declare that the following, taken in connection with the drawings which accompany and forinpart sufficient to enable those skilled in the art to practise it. The invention relates to details of construction of that class of gas-burners in which provision is made of a current or currents .of air, which, commingling withthe-gas, form, when ignited, a blue and intense heat giving ilaine,'in contiadistinction to the yellow ame made by ignited gas alone, which latter iame has a reater illuminating but less heat-giving power.

The object of my present improvements is to simplify and cheapen the constructionof such burners, and to increase their efficiency in consuming, to a maximum heat-giving advantage, ccmmingled gas and air.

My improvement consists, first, in making the burner with a surmounting flat-roofed gas-chamber or dome, having eduction-o jiiices just under the roof, and having the air and gas-tube extending up nearly to the under side of the roof, the mouth of the tube delivering the gas directly against the heated plate forming Athe roof, said gas expanding and filling the chamber, and' being driven out through the orifices, so that being then ignited, the burning jets are driven, as from,a blow-pipe, directly against thebottom surface of any vessel placed over the burner.

`The invention also consists in casting the burnerintegral, or solid in one casting.

Also, in making the dome .fiat-topped, (the ediictionorifices being on the sides so that the vessel to be heated may rest or be placed directly on top of the burner. n

i The drawing represents a view of my improved bui-neig, half in elevation and half in central section.

, a denotesvthe burnertube,`having at its l'ower end the screw-,thread b, for attaching the burner to the gas-pipe. v n I Just above this screwfthread is a horizontal partifroin the tube impinging against the heated surface of the plate h, 'and expanding'and filling the vchamber g, issuing through the jet-holes with pressure created by such expansion, so that the iiame ofthe ignited jets impiuges with force against the bottom of a vessel placed directly over the burner, and quickly heats the contents of the vessel.

'Io-bring such a vesselinto immediate proximity lwith such inflamed jets, I make the top of the plate h ilat, as seen in the drawing, so that a vessel may rest and be supported directly upon the burner.

the tube a and dome. fin one piece, so as to obviate the fitting or screwing -of one part upon the other, and I'also cast he pa 'tion or diaphragm cin the tube.

I claim, in combination with the burner-tube a and 'the expanded ga -chamber g, (having flame-orifices at its sides and near its top,) the extension of the tube a up through the chamber, the tube opening at itsa top directly beneath the at roof of the chamber, all substantially as described.

I also claim the combination of the dome f and tube a in one casting, substantially as described.

I also claim `forming or casting the diapraghiu c integral with the tube, substantially as shown and described.
